Paper Abstract

The Naval Research Laboratory has developed a novel one-sided NDE system for inspecting steel reinforced rubber sonar domes without drydocking. The submersible x-ray system scans the dome through an aluminum window in contact with its surface and uses collimated backscatter imaging to create tomographs of the dome structure. In this paper we discuss backscatter imaging, describe the system, and present results from in-situ inspections of sonar domes on several frigates.
